To all whom it may-concern.-

Be it known that I, GEORGE A. ENSIGN, a l citizen of the United States, and a resident of Defiance,in the county of Defiance and State of Ohio, have invented a new and Improved Planing-Machine, of which the following is a full, clear, and exact description. The. invention relates to woodworking ma- 1 chinery, and more particularly to planingapparatus such as shown and described in the; Letters Patent of the United States No. 557,327., .granted to me March 3], 1896. The object of the invention is to provide a i new and improved planing-machine for planingifellies cutfrom the solid wood and with, out danger of splitting or roughening the in-f ner and outer peripheral surfaces. :The invention consists of novel featuresl and parts and combinations of the same, which will be more fully described hereinafjterand then pointed out in the claims.

-J=forming a .A, practical embodiment of the invention i 'isrepresented in the accompanying drawings, part of this specification,- in which i similar characters of reference indicate corresponding. parts in all the views.

- Figure 1 is a plan viewof the improvement. Fig. 2' is an enlarged sectional side, elevation .of. the-felly-feeding device. parts being broken out. 'Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. 4 is a cross-section of the centering device, the section being on the lined 4 of Fig. 1. Fig. 5 is .a plan view of one of the centering-fingers,

and'Fig. 6 isa face view of one of the cutter .of the cutter-head.

The spaced cutter-heads A and A of the planing-machine are mounted to turn in the usual manner aboveafeed-table B, on which is mounted acentering device 0 for centering ajf'elly D previous to its passage between the cutter-heads A and A for the latter to plane the. inner and outer segmental faces thereof. Thef elly D is moved'from the centering device C over'the table A and between the outter-heads A and A while in a-centered posi- .tion, so that the cutter-heads pro erly plane theinner and outer segmental sur aces of the :said felly, the latter during its passage between the c utter-heads A and A also traveling over the usualfeed-roller E, located be tween the cutter-heads A and A and having its top approximately flush with the top of l the manner described, a manually -controlled the. table B. In order to move the felly D in;

feed device F is rovided, adapted to take hold of the felly l at the centering device O and carry it inthe centered position between the cutter-heads for the latter to plane the same. v

The centering device O is arranged as follows: On the table B isfasteneda bracket G, having elongated grooves -G, through which extend bolts G screwing in the feedtable for securing the bracket G in position thereon and for allowing transverse adjustment of the said bracket. In the bracket G is secured an arm H by the use of a set-screw H, and on the said arm, on opposite sides of the bracket G, are fastened collars Iby setscrews 1, and on each collar is pivoted a finger J, adapted to be engaged bythe inner face of the felly D, as plainly indicated in Fig. 1. Each of the fingers J is provided with an offset J, connected with one endof a spring J attached at its other end to the col lar I, so as to allow the finger J to yield in one direction to compensate for any unevenness or roughness on the innerface of the i felly D. A lug J on the ofiset J and adapt ed to abut against thecollar I serves to limit the swinging motion of the-finger J in a reverse direction.

By the arrangement described the bracket G may be transversely adjusted, while thecollarsI, carrying the fingers J, may be each independently adjusted on the arm H, so astobring the terminals of the fingers J in proper position relative to thearc of the circle of the inner face of the felly D relative to the 'cutter-heads A r and A.

The feed device F is. arranged as follows: A'guideway K' is bolted or otherwise secured to the table B, and on the said guideway K is mounted to slide longitudinally a base K,

' in which is mounted to turn the foot L of a standard L, provided with a plurality. of apertures L located one above the other, as plainly shown in Fig. 2, and engaged by a pivot N, on which is mounted to swing a head N, in which is held longitudinally adjustable an arm 0, adapted to be fastened in position on the said head Nby a set-screw N The forward end 0 of the arm 0 is provided with a transversely-extending holder P, fastened in place by a set-screw P, and on the said holder P are secured carriers Q, fastened in position by set-screws Q, and

each of the said carriers Q is provided with a prong R, extending downwardly to engage the top surface of the felly D. Each of the prongs R is adjustably secured in the corresponding carrier Q by a set-screw R, and as each carrier Q is ad ustably secured on the holder P it is evident that the two prongs R can be adjusted any desired distance apart, and the prongs R can be adjusted lengthwise in their carriers to Iproperly engage the top surface of the felly at or near the middle thereof. By engaging the pivot N with any one of the apertures L it is evident that the head N, and consequently the arm and the parts supported thereby, can be raised or lowered to bring the points of the prongs R in proper contact with the top surface of the felly D, according to the latters thickness.

In order to limit the swinging motion of the arm 0 and its head N, a stop S is pro vided, adjustably secured by a set-screw S on a bracket L bolted or otherwise fastened to the standard L, and the upper end of the latter is provided with a nut L in which screws a screw-rod T, adapted to engage the top of the holder 0, so as to fasten the latter in position between the stop S and the setscrew T to hold the arm 0 against swinging movement.

Each of the cutter-heads A and A is provided with cutters A each of which has its cutting edge A (see Fig. 6) notched or serrated, the serrations of the cutting edge of one cutter A being out of alinement with the serrations of the next adjacent one on the same cutter-head A or A. As the felly D to be planed at its inner and outer surfaces is cut from a solid piece of wood and not bent,

it is evident that when the felly D is assed between the cutter-heads A and A t e serrated cutting edges A plane the inner and.

outer surfaces without danger of chipping the same or otherwise producing roughened surfaces. It is understood that straight cutting edgesthat is, such without serrations or n0tchesare liable to chip the surfaces of the felly D as the cutting edges cut against the grain of the wood.

The operation is as follows: The felly D is placed by the operator on the table B and with its end surface against the fingers J of the centering device O, as plainly illustrated in Fig. 1, and then the operator swings the feeding mechanism F around so that the rongs R engage the top surface of the felly D, as plainly indicated in dotted lines in Fig. 1. The operator now imparts a swinging motion to the feed device F in the direction of the arrow a, (see Fig. 1,) so that the felly D is carried along over the table A and helped by the prongs R into a centered position and while in this position is passed etween the cutter-heads A and A, so that the cutters A lane the inner and outer surfaces of the felly true without danger of chipping the said surfaces. In case the inner surface of the felly D is irregular, then the fin ers J yield suflicientlyto permit proper trave of the felly D without losing its centered position. For fellies D of different widths it is necessary to adjust the bracket G transversely to bring the fingers J in proper relation to the felly D, and in case the thickness of the latter varies it is necessary to adjust the pivot N of the head N in the standard L to bring the points of the prongs R in roper relation'to the upper surface of the fe ly D. For fellies D having different radii it is necessary to adjust the base K longitudinally on the guideway K and to adjust the arm 0 correspondingly in a lengthwise direction in the head N, so that the pron s R engage the felly D at or near the middle 0 the top of the felly D.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent 1. A felly-planing machine, comprising a table, a rotatable standard mounted'thereon,
